2 out of 5 eggs

Pros: Works in linux excellently as well as bios... better than asmedia and silicon image sil3125 chipsets. 220MiB/s read aggregate from the card with 7 drives... choosing any subset seems to give this same number which is decent/high for a multi-port sata card.

Cons: Does not fit into my thermaltank elements s case and stay level with my gigabyte ex58 ud7 rev 1.0 pci-e connectors. I'm not sure if this is a defect/bad QA or not but basically I can't screw down the card or even put it level without the other side rocking out. I've not had this issue on any other card. Syba, your thoughts?

Manufacturer Response:

Dear customer,

Please check the bottom part of the bracket, maybe it's touching something in your case? Compare our card with your other cards and see if the bracket is the problem.

All the cards are made with advanced SMT machines and very unlikely the bracket will be mounted incorrectly. However, please contact our customer service department for a replacement if you like. SYBA offers an on-line RMA form, the user can easily fill out the form and submit it for a quick RMA return and exchange.

Our technical support team is available to help 9am-5pm M-F. Feel free to contact us during those business hours at

We apologize for any issues that you are having. As you know we are more than happy to provide our customers with a hassle free exchange when a product is defective.

Thank you for purchasing one of our products, and for leaving us your valuable feedback. We value all positive and negative feedback.

Regards, SYBA CST 01042013

2 out of 5 eggsUnreliable

Pros: Originally it connected fine to my ProBox 4 Bay Hard Drive Enclosure and worked at full speed

Cons: The card BIOS only saw a single drive. Windows saw all 4 and was able to soft RAID. After a few months the performance slowed down considerably. The drives held a few Exchange mail databases and was so slow the PC would not restart properly after updates and caused dirty shutdowns of the databases and caused data loss. Moving the databases took hours to perform a restore of backup. The card is now not functioning correctly and does nnot work for its intended purpose.

Other Thoughts: Save your money and purchase something else if your data is important.

1 out of 5 eggsWon't Start - Code 10 on Win 7, 64 Bit

Pros: Too soon to tell, won't install

Cons: Device won't start on Windows 7, 64 Bit. Worse yet at one point it trashed the Partition Table on my systems hard drive so the system had to be re-initialized.

1 out of 5 eggsCauses Reboot when formating

Pros: None.

Cons: Wasn't recognized on one computer, did show up on another one. Tried setting up Raid 1 in the boot utility - but hitting F10 to Save/Exit only saves, nothing I did would exit. Finally had to ctrl-alt-delete to get out. Restarted the system, fdisked the drive, but then while formatting, my Ubuntu system rebooted. I can't remember the last time that happened.
